Smoking, Obesity Make RA Harder to Control

Remission in RA patients can be harder to achieve in those who are overweight or smoke, according to a recent study. American and Canadian researchers who collected data on more than 1,100 patients receiving standard treatment for RA found that sex (being female), excess weight and smoking were not significantly associated with symptom severity early on. However, all three factors influenced how much symptoms improved over time. The most dramatic differences in symptoms were seen in patients who were overweight or obese and smoked, the study found.

Obesity Reduces Odds of RA Remission

Research suggests weight may be a factor in whether people with RA will achieve disease remission. A review of studies screened a total 3,368 patient records. Canadian researchers found obese patients with RA were less likely to achieve remission or sustain remission compared to healthy-weight patients. Obesity, they reported, negatively impacts disease activity and patient-reported outcomes during therapy. Therefore, they say, interventions to reduce BMI should be investigated for the ability to improve disease outcomes.

People with rheumatoid arthritis (RA) who are obese are less likely to achieve disease remission than their non-obese counterparts, according to a meta-analysis published in May in Arthritis Care and Research. The review also found that obesity was associated with higher levels of disease activity and pain, suggesting excess weight may negatively affect overall outcomes in RA. This meta-analysis supports earlier research, including a study presented at the 2015 annual meeting of the American College of Rheumatology.Continue reading New Research: Obesity May Reduce the Chance of RA Remission by as Much as Half→
